Intermediate levels of Re(ƒ)=constant are shown with thin red lines for negative values and with thin blue lines for positive values. have a peek here

Cody's rational Chebyshev approximation algorithm.[20] Ruby: Provides Math.erf() and Math.erfc() for real arguments. This allows one to choose the fastest approximation suitable for a given application. J. Negative integer values of Im(ƒ) are shown with thick red lines. https://en.wikipedia.org/wiki/Error_function

Esta función, llamada w(x), (también conocida como la función Faddeeva) admite la siguiente expresión: w ( z ) = e − z 2 erfc ( − i z ) {\displaystyle w(z)=e^{-z^{2}}{\textrm This usage is similar to the Q-function, which in fact can be written in terms of the error function.

En forma similar, las En para n pares luego de dividirlas por n! Perl: erf (for real arguments, using Cody's algorithm[20]) is implemented in the Perl module Math::SpecFun Python: Included since version 2.7 as math.erf() and math.erfc() for real arguments. Related functions[edit] The error function is essentially identical to the standard normal cumulative distribution function, denoted Φ, also named norm(x) by software languages, as they differ only by scaling and translation. En menos infinito, tiene el valor de -1. Error Function Matlab

La función error evaluada en más infinito tiene el valor de 1, exactamente (ver Integral de Gauss). It is defined as:[1][2] erf ⁡ ( x ) = 1 π ∫ − x x e − t 2 d t = 2 π ∫ 0 x e − t Generated Mon, 17 Oct 2016 02:46:46 GMT by s_wx1131 (squid/3.5.20) ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: Connection http://imagextension.com/error-function/funcion-error-complementaria.php Go: Provides math.Erf() and math.Erfc() for float64 arguments.
